mcpm - MCP Package Manager

A CLI tool to install and manage Model Context Protocol (MCP) servers for Claude Code and Gemini CLI.

Features

• Easy Installation - Install MCP servers with a single command
• Multi-Platform Support - Works with GitHub and GitLab
• Auto-Detection - Automatically detects project type (Node.js, Python, Go)
• Build Automation - Handles dependencies and build steps automatically
• Multi-Client - Register servers with Claude Code and/or Gemini CLI

Installation

From Source

git clone https://github.com/spre-sre/mcpm.git
cd mcpm
go build -o mcpm .

Move to PATH (optional)

sudo mv mcpm /usr/local/bin/

Usage

Install an MCP Server from Repository

# From GitHub
mcpm install @modelcontextprotocol/server-filesystem

# From GitLab
mcpm install gl:@gitlab-org/my-mcp-server

# From direct URL
mcpm install https://github.com/user/repo.git

# Install globally (available in all projects)
mcpm install @modelcontextprotocol/server-filesystem --global

Add an Existing MCP Server

For HTTP endpoints or already installed servers:

# Add HTTP server
mcpm add sentry https://mcp.sentry.dev/mcp --transport http

# Add SSE server
mcpm add slack https://mcp.slack.com/sse --transport sse

# Add local stdio server
mcpm add myserver /usr/local/bin/my-mcp-server

# Add with environment variables
mcpm add myserver node /path/to/server.js -e API_KEY=xxx

# Add only to Claude Code
mcpm add myserver /path/to/server --claude

# Add only to Gemini CLI
mcpm add myserver /path/to/server --gemini

# Add globally (available in all projects)
mcpm add myserver /path/to/server --global

Remove an MCP Server

# Remove from both clients (current directory)
mcpm remove myserver

# Remove only from Claude Code
mcpm remove myserver --claude

# Remove only from Gemini CLI
mcpm remove myserver --gemini

# Remove from global configuration
mcpm remove myserver --global

Update an Installed Server

Pull latest changes from remote and rebuild:

# Update a specific server
mcpm update server-filesystem

# Update all installed servers
mcpm update --all

# Update and re-register globally
mcpm update server-filesystem --global

List Installed Servers

mcpm list

URL Schemes

How It Works

1. Clone - Fetches the repository to .mcp/servers/<name>/
2. Detect - Identifies project type based on config files:
   • package.json → Node.js
   • requirements.txt or pyproject.toml → Python
   • go.mod → Go
   • mcp.json → Custom manifest
3. Build - Installs dependencies and builds the project
4. Register - Adds the server to your chosen clients (Claude Code / Gemini CLI)

Supported Project Types

Node.js

• Detects package manager (npm, yarn, pnpm)
• Falls back to npm if preferred manager unavailable
• Runs install and build scripts
• Supports monorepo structures

Python

• Creates virtual environment (.venv)
• Installs from requirements.txt or pyproject.toml
• Auto-detects entry point (main.py, server.py, etc.)

Go

• Runs go build
• Outputs binary as mcp-server

Custom (mcp.json)

Create an mcp.json in your repo root:

{
  "type": "node",
  "buildCmd": "npm run build",
  "runCmd": "node",
  "args": ["dist/index.js"],
  "requiredEnv": ["API_KEY", "SECRET"]
}

Configuration

Claude Code

Servers are registered using claude mcp add command, which stores configuration in ~/.claude.json under the project path.

Gemini CLI

Servers are registered in .gemini/settings.json in the current directory:

{
  "mcpServers": {
    "server-name": {
      "type": "stdio",
      "command": "node",
      "args": ["/path/to/server/index.js"]
    }
  }
}

Requirements

• Go 1.23+ (for building from source)
• Git
• Node.js/npm (for Node.js servers)
• Python 3 (for Python servers)
• Claude Code CLI (for Claude Code integration)
